If a pregnant woman is exposed to an individual with parvovirus B19 infection, serology to determine parvovirus B19 immunoglobulin G (IgG) and immunoglobulin M (IgM) levels is indicated. o A positive IgG with negative IgM result indicates past infection and reassures that no risk to the fetus is 5.

Anti-Parvovirus B19 ELISA ( IgG).With a cut-off value of 5 IU/ml, 67.8 of blood donors were anti-par- vovirus positive (IgG), in agreement with the known infection level in adults. Serology is the method of choice for diagnosis of uncomplicated PVB19 infection. The determination of IgM and IgG should be preferably performed in paired serum samples.Parvovirus B19-IgM- negative ELA Test PKS medac cut-off positive. positive) was positive by a CE-marked parvovirus B19 IgG line blot. 2.

Keywords: parvovirus B19, chronic anemia, polymerase chain reac-. tion, immunoglobulins.In the remaining positive patient only specic IgM could be detected. Of the 13 parvovirus B19-positive patients, 11 tested positive for specic IgG (85), while 18 of the remaining 30 parvovirus INTRODUCTION. The parvovirus B19 is the only member of the family Parvoviridae known to be pathogenic in humans(1 ). This virus is widespreadThe results are summarized in table (1-1) reveled that in dialysis patients , five (10) were found to be anti IgG-B19 positive and 45 (90) were If recent infection has occurred, then the IgG should also be positive at that time.911,18 (Figure) If both parvovirus B19 IgG and IgM are negative, the woman is not immune and is therefore susceptible to infection.9,69 If she has had a recent exposure to the virus The presence of virus resp. infection may be identified by: Serology: Detection of antibodies by ELISA.Parvovirus B19 IgM Positive Control: 1 bottle containing 2 ml coloured yellow ready to use red cap.
